CHARLES H. PATTEN,'OF PROVIDENCE, BHODE ISLAND, -AS$IGNOR TO CHARLES E. HANCOCK COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHQDE ISLAND.

To all whom it may concern. 1

Be it known that I, CHARLES H. PATTEN, a citizen of the United States, andresident of the city of "Providence, in the county of Providence and St-ateof Rhode Island, have invented certain new and useful Improvements in EXpansi-ble Bracelets, of which the following is a specification. This invention relates to expansible bracelets and has for its object to provide in such a bracelet a plurality of extendible links each having ,two longitudinally movable members connected together on opposite. sides with coil springs, said movable mem bersbeing mounted betweentwo relatively fixed trough-like side members. By this construction two light coil springs are provided in each extendible link so that if for any reason one of said springs should break, then the second spring would still remainE 'render that link effective.

- appended claims.

With these and othe r objects in view, the invention consists of. certain novel features of construction, as will be more fully described and particularly pointed out in the Of the accompanying drawings: Figure l is a view of an expansible bracelet constructed of myimproved extendible links. Fig. 2 is an enlarged plan View of two of the extendible links connectedtogether by-a short link, one of said extendible links being in section. 'Fig. 3' is a side elevation, greatly enlarged, of one of the links-sectioned on line 33- of Fig.2, showing the guiding bars and arms which form bearings for the sliding linksl Fig. 4- is a perspective view showing a portion of one of the side members with a'connecting guide pin extending from one endthereof. l igL 5 is a perspective-view. showing the two extendible members operativcly' connected together 'by'the coil springs, one on either side thereof and theside members removed.

Referring to the drawing, designates the expansible bracelet which is perterably made up of a combination of comparatively long extendible links 11 of my improved construction, joined together by comparatively short non-extendible links '12 whereby the bracelet is adapted to be expanded or made larger'so as to readily passfover the end onto the arm of the wearein" Each of these extendible links is made u'p with an outer shell portion-Which is constructed of through the" center portion of members 19 E P-ANsIBLE BRACELET.

Specification of Letters Patent. Pat nt if Application'filed May 13, 1912.. Serial No. 636,856 I two elongated trough-shaped side members 13-13 each having its inner surface open land deep grooved as atlet, and having a closing back and end plate15 and 16 respec tively. The open portions ofthese side members are turned inward toward each other and their ends are spaced apart and permanently secured together by means of the crcssbars l? and 1S liked at each end thereof by solder'or otherwisen i At 19 and 20 are the two oxtendible ineinhers which are themselves preferably made of broad .tlat stock bent into "a link form,- each having a hollow middle portion 21, 22; These members are mounted end to end between said side frames .13, the cross bars 17 and 18 fitting closely in and extending and 20, serving to provide a-bearing a't gif' end tor guiding thesejinembers j 1 a. second bearingi or slidably supporting the opposite ends of each of these members 1 have inserted anotherpair of bars -or arms 23 and 24 and fixed. them one/in each of these sliding members so that their opposite ends will extend outward laterally there from and enter and slide in the groove p'on tion 14; in both side members, which second bearing'holds these extendible members in perfect alinement with the shell or side members. Elhe ends of each of these cross arms are slightly reduced as at 25 to receive the ends of the wire of the coil springs 26 and 27, which are arranged on either: side of said memberswithin the'body of each side member with their jopposite ends'connected to the' corresponding ends of both of said bars, by means of which .thcse extendiblemembers l9 and 20 are yieldingly held in contracted position. In assembling the parts of this link the arms 23 and Q-lare secured by solder or. otherwise to their re.

spective members, the springs 26 and 27 are then attached to said arms,.then the side members 13-43 are positioned with the ex tendiblemembers between them, and the cross bars, :17 and '18 soldered in positior and the link is completed. This extcndibk link may beconnectcdto tlie'next extondible H link by any suitable connecting member 12 By my improved construction it Wlll be .seen that by the use of two springs acting independently upon each of said extendible members, if one should be broken for any said side reason there would still remain the second 1 spring to render the link operative, thereby I providing a very practical and eflicient racelet ink with practically double the life I and wearing power of the ordinary link= where but a single spring is employed.

I claim:

1. A bracelet constructed of a plurality of compound extendible links, each of said. links comprising a shell constructed of two trough-shaped side members spaced apart and rigidly secured by a cross bar extending between them at each of their opposite j ends, two elongated band members positioned end to end mounted between said side members to slide longitudinally on said cross 1 bars, a guide bar fixed to and projectingi laterally from each side of each band into members, and a spring secured to l and leading from each end of said arms and attached to corres onding ends of the arm 1 in the other band to yieldably hold both! bands in contracted position.

2. A bracelet constructed of a plurality of i compound extendible links connected together ,each' of said links comprising two trough-shaped side members spaced apart and rigidly secured by a cross bar extending between them and fixed to each of their ends, two elongated band members having hollow center portions mounted between said side members to slide longitudinally on said cross bars, a guide bar fixed to and extending laterally through each of said band members into each of said side members, and a spring located in the trough of each side member secured to and leading from each end of said arms and attached to corresponding ends of the arm in the other band to yieldably hold both bandsin contracted position.

In testimony whereofI afiix my signature in presence-of two witnesses.
